WILI'JIAM GORDON, 0F BOSTON MASSACHUSETTS, ASSIGNOR TO UNITED SHOEMACHINERY COMPANY, OF PATTERSON, NEW JERSEY, A CORPORATION OF NEWJERSEY.

Specification of Letters Patent.

To all iohom it may concern:

Be it known that I, VViLLIAM Goanox, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Machines for MakingInsoles; and I do hereby declare the following to be a full. clear, andexact. description of the invention, such as will enable others skilledin the art to which it appertains to make and usev the same.

The present invention relates to machines for making insoles, and morearticularly to a featheneclging or edge-hove ing attachment. for insolechanneling machines.

In the manufacture of insoles the stock is first cut up into blankshaving the shape of the completed sole and these blanks. are then passedthrough a channeling machine which cuts a channel in one surface of thesole and simultaneously forms a lip or channel llap and which alsoeither splits the edge of the blank to form another lip or removesa'portion ofi'he stock from the edge of thochain neled surf a e of thesole to form a shoulder at the baseof the channel flap or lip. Insolesmade in this manner present a sharp cd e at the margin of thounchanneled or .un l ipped surface of the sole, which edn'e tends to cutthe lining); and upper of the completed shoe. Also when the shoe is wornthe margin of the insole sometimes curves upwardly and this sharp edgeforms a ridge upon the inside of the shoe which renders the shoeextremely uncomfortableto the foot of. the wearer. To remove this sharpedge the margin of the unlipped or unchanneled surface of the sole issometimes beveled, the

'beveling being performed as an operation separate from the operation ofchanneling ,the sole. This separate operation, however, adds to the costof manufacture and some quently is usually omitted.

The object of the present invention is to provide means whereby the edgeof the unlipped on 'unclianneled vsurface of the sole can be beveledsimultaneously with the formation of the channel and lip or lips, sothat an insole having the edge of its unchanneled or unlippedsurface'beveled can be produced without subjecting the sole to aseparateoperation andwithout adding tothe cost of manufacture. With thisobject in view the present invention contemplates the provision in a anchine for making insoles provided with a li forming knife or knives, ofa bevelino' knife arranged to act on the edge of the unlippcd surface ofthe sole. The lip forming knife or knives may he of any usual orsuitable shape and arrangement, as the invention. broadly considered,contemplates the use of a beveling knife arranged to act on the edge ofthe unlipped surface of the solo. in combination with either achanneling knife which cuts a channel and forms a lip or channel flap,or in combination with an edge splitting knife or knife for forming ashoulder at the edge of the sole.

In insole channeling machines the edge gage is usually movably mountedso that. it can be moved during the operation of the machine to vary theposition of the sole edge with relation to the lip forming knife orknives. It is desirable that the bevel formed at the edge of theunlipped surface of the solo be uniform throughout, and accordingly. inthe preferred form of the pres I {embodiment of the inventionhereinafter described, the movement of the beveling' knife with the edgegage con \cniently produced by mounting the knife upon the gage.

In addition to the features of invention above referred to, the presentinvention also consists in certain constructions and a rrangenient ofparts hereinafter described in whicha Figure 1 is a view in sideelevation of a portion of the insole channeling machine with thepreferred form of the invention applied thereto, so much only of themachine being illustrated as is necessary to show the connection of thepresent invention therewith. Fi'g. 2 is a sectional plan viewillustrating the relative arrangement ofthe work support, the feedwheel. and the ohanne-lin'g and beveling knives. Fig. 3 is an end viewof the edge gage with the support for the unlipped surface of the soleand the bevcling knife mounted thereon. Fig. i is :1 i i:-

The beveling knife is indicated at; T, and as illustrated nomprises ashank. portion curved in the arc of a pircle and provided at one endwith a cutting edge 8. The upper surface of the knife grooved, as isclearly shown in Fig. 10, and the edge 8 formed by a bevel on the lowerside of the knife so that the edge of the knife is curved and acts toproduce a rounded edge on the nnlipped surface of the sole as indicatedat 9 in Fig. 4. The heveling knife is mounted upon a. knife carryingblock 10 which is provided with a curved-knife receiving guidewav It.the upper surface of the knife being recessed as indicated at 12 toreceive a projecting flange, 13 of the guidcway. A cl'an'iping'plate 14is secured to the block 10 lay screws 15 and frictionally engages thehevcling knife so as to securely hold it in any position to which it isadjusted. The knife carrying block 10 is mounted upon the edge gage ofthe inach ine will he hereinafter described.- the hcveling knife beingm'l'fingl'd in a l'lOtlZOiltal plane with its cutting edge extendingtransversely to the direction of feed, The position of the knife in themachine will be clearly understood from an inspection of Figs. 1 and andit will he soon that by adjusting the knife on its guidcway in the hlockit). the cutting edge ol the knife will be adjusted in the direction ofteed. The

cutting cdgeol tln knitccan ihns holn'onght,"

18 pro ided with a, horizontal lip ll) the edge gage and block 18 andscrewing into the block 10. The cutting edge of the hex-cling knife canthus be adjusted in the plane of the sole transversely to the line offeed by adjusting the block 18 on the edge gage 21. and the cutting edgeof the knife can be adjusted in a direction perpendicular to the planeof the sole by adjusting the block 10 upon the block 18. By means ofthese adjustments the cutting edgeof the knife can he brought into aposition to act properly upon the edge of the unlipped surface'of thesole and remove any desired:

amount of stock therefrom.

The edge gage 21 .is mounted in the. same unlipped surface of the soleis uniform throughout. 7 v 1 In order that the bevelin'g knife may actwith 'certainty to remove the skiving from the edge of the sole, it. isnecessarythat means in addition to the Work support be provided for suiporting' the unlippcd surface or the sole in proximity to the knife.

In the illustrated embodiment of the inven tion accordingly, :1 support23 has been provided which. as shown, consists of a plate formedintegral witlr or secured to the edge gage. This plate projects from theedge gage beneath the sole and is received in an annular recessQd cut inthe periphery of the main .work support. The plate 23 moves with theedge gage and thus serves at all.

times to support theunlipped surfaceof the solo/m proximity to thecutting edge of tho howling knife.

The operation of. the machi in the drawingswill be clearly understoodfrom the description ahove givcn of the construction and arrangement ofthe various parts. and it need only be stated that as the insole is fedthrough the machine the channeling knife acts'to"forii1 the channel" 259:rrcd cinhodiincnt of-the invention having ne illustrated l been is 1.A machine for making insoles, having, in combination, a lip formingknife, and a beveling knife arranged to act on the edge of the unlippedsurface of the sole.
